When we buy a new smartphone, we will also get a wall charger for the phone. Actually, we can use other charger models for powering the phone. When our basic wall charger has something wrong, we will get new chargers. We need to consider when and where we will charge our devices. There are even chargers even powered by different energy sources. We can get a spare charger in case of loss or breakage. We can get a solar cell phone if we are often on the go.
The first thing we need to consider upon getting a charger is compatibility. There may be some chargers that just fail to be plugged into our phone. If we do not want to be bothered with this problem, we can turn to micro-USB charging port. Of course, some of the phones will not be compatible with the mini USB chargers.
With so many options of charger, how to make the decision? It is really no need to prepare all of those new types of chargers available in the market. We can see the chargers nowadays updated in the market have some basic features. Some are best for home or office use while some are designed specifically for the car. For those people who have trip often can choose a charger that runs on an alternative fuel source. In an emergency, a battery-powered cell phone charger could potentially save a life. If we have more devices but not enough chargers, we can try docking station that can charge more devices via the USB ports at the same time.
As for the charging docking station, the phone can slip into the docking station via charging port. It’s very convenient to use the docking station for we can still use the phone while it is in charge. We can see some of the docking stations with speakers for listening to music stored on the phone. We can charge devices via docking station with multiple ports with our family members at one time. several mobile devices to charge at one time. Similar to docking station, we can use charge mats for convenient charging, and the charging mat has no direct port connection.
If we are often on the go, we can get vehicle cell phone chargers or charging adapter for the vehicle. Our car charger can power the smart phone via the vehicle’s battery. During a trip to different countries, we don’t have to worry about varying voltages if we have chargers that can run on alternative energy. It’s efficient. Here comes an even more eco friendly charger - solar charger. The solar charger can store the solar power in a battery for later use. When we get solar panels, we need to know they differ in efficiency. The solar charger usually comes with various adapters for maximum compatibility, but the only disadvantage is the dependence on direct sunlight. If there is no sunlight and we are also outside without electricity power, how to charge the electronics? We can use hand crank cell phone chargers. They can be of great help in emergency situations and inclement weather since they are powered by hand, with electricity being generated via our own muscle power.
The chargers are just updated at a very fast speed.When looking for a new phone charger, the importance of device compatibility cannot be stressed enough. Aside from that, we need to consider our habits and lifestyle to determine when and where we most often need a charge.

Difference Between USB 2.0 & 3.0 Device
What type of USB hub are you currently using now, USB 2.0 or USB 3.0? In the digital market, we can find a lot of USB 3.0 devices and the popularity of USB 3.0 derives from its advantages over USB 2.0 in various aspects, such as very high data transfer rate, higher power availability, better power management, etc. Besides, the USB 3.0 devices can still work compatibly with USB 2.0 devices, hubs or other ports. When the PC users need more USB 3.0 ports than their PC or docking station provides, there is external USB 3.0 hub available.
We know the updating of USB 3.0 from USB 2.0 is partly for the speed. Then how much faster is USB 3.0? Can it realize a great improvement if we upgrade our old USB 2.0 flash drives? Let’s have a further look at the difference between the two different USB hubs.
In aspect of theoretical maximum signaling rate, USB 2.0 can provide a rate of 480 megabits per second, while USB 3.0 5 gigabits per second. In this way, USB 3.0 is theoretically faster than USB 2.0. But in reality, this standard just specifies the maximum data transfer rate via a USB port. USB drives will be obstructed by the speed of their flash memory. In the real world, the worst USB 3.0 drive was faster than the USB 2.0 drives, but only by a tiny bit. Or even some of the USB 3.0 drives are known to perform at similar speeds to USB 2.0 devices.
Then let's come to their price difference. Price is a huge factor that differentiates the USB 3.0 and USB 2.0. We can find a lot of USB 2.0 flash drives offered at very cheap price in the market, and maybe $10 is enough for getting a decent 2.0 flash drive of 8 GB USB. But for a USB 3.0 drive, we need to spend around $40. If you just need a small and cheap drive, USB 2.0 is enough. If you want a hard drive that is used frequently, and transfer speed is what you care much, choose a USB 3.0 drive. In general, the faster the USB device is, the more expensive their price will be.
As a fantastic upgrade of USB 2.0, some types of USB devices are not that fast, such as USB mouse or USB 3.0 keyboard, with no improvement in input speed. Nevertheless, USB 3.0 will take place of USB 2.0 devices. Given the backwards compatibility, we can switch to USB 3.0 devices. But also, we can save dollars by just plugging USB 2.0 devices into USB 3.0 ports.
